ChatGPT Habits That Actually Cut Daily Work Time In Half

People are only using a small part of the capability of ChatGPT. They enter a question, listen to the answer, and then close the tab. The habits that really save time are different; they are putting in place some context the first time, eliminating repetitive tasks by creating reusable prompts, and using the tool to come up with a finished product instead of one that needs an extra hour of editing.
Set Up Custom Instructions Before Anything Else
Why Starting From Zero Every Time Wastes Your Time
Each new chat session with ChatGPT begins anew, without any memory of the user, their writing style, or their tasks. Re-explaining your context takes up a lot of time over the first 5 minutes of a session. Custom instructions get the job done by allowing you to have a background that will be automatically loaded in all conversations.
What To Put In Them
There are two parts of the instructions. The latter is what you want ChatGPT to know about you: your role, your industry, your audience type, and preferences that impact the way you interact with it to help. The second one is about how to do it, including whether to come up with short or long answers, whether to avoid disclaimers, and whether to write prose or bullets. These can be set up in 5 minutes and will take away the need to explain yourself at the beginning of each session.
Use Projects for Recurring Work
What Projects Actually Do
Projects hold files, instructions, and conversation history for all conversations and can be shared across all conversations in a project. Your brand voice guide, previous examples, and list of ongoing topics may be in a content project. A client project may include their preferences, a summary of previous work, and their background. Whenever you open that project, ChatGPT already has all the content it requires.
The Time This Saves In Practice
The document is not uploaded, but instead the context is re-explained each session, and the actual task is begun. The setup time of one project fully pays for itself within the first 2 or 3 uses for anyone who works with the same type of work frequently.
Build A Prompt Library For Tasks You Do Repeatedly
Why Rewriting Prompts Wastes Time
If you develop a good prompt for a task and type a poor one the following week, you are wasting your time and getting inconsistent results. If you write a useful prompt to write a weekly update, to summarize a meeting, or to draft a client email for some recurring task, you save it in a simple document that you can paste into any new document without having to think up a whole new prompt for each new task.
How To Build One Without Much Effort
If you have used ChatGPT to generate something usefully, duplicate the prompt and store it in a new file using a succinct label. After a few weeks, a library of successful prompts is developed that cover most of your regular tasks. The prompts don't have to be complicated. The best ones are generally specific in format, length, and tone and not long.
Turn Rough Notes Into Finished Output
The Technique That Removes Most Editing
If you have some ideas in your notes, bullet points, or transcript from a voice memo, paste it into ChatGPT and let it arrange and build them into a complete draft using your voice. The result is more likely to be the kind you want since it is created from your ideas and not an empty slate.
What To Include In The Prompt
Tell it to the audience, format it, and lengthen it, and include 1-2 examples of your writing in the past so it can sound like your writing style. By asking it to use your examples as models for your style instead of abstractly describing your style, you get vastly better first drafts with little need for editing.
Use It As A Thinking Partner, Not Just A Writer
Getting Unstuck Faster
If a problem becomes murky or if a decision feels difficult, it can be helpful to explain it to ChatGPT and ask it to find the core tension or list the tradeoffs that often come up. It's not that the output is always correct; it's that you have to break down the problem into the words and get a structured answer to the problem that makes you think about it more.
Ask For Weaknesses In Your Own Plan
By copying and pasting a proposal, decision, or publication into ChatGPT, you will reveal issues that you might not have noticed when working on the content yourself. This only takes 2 minutes and often will help you find something that needs to be addressed.
Automate Email and Message Drafting
The Setup That Makes This Fast
If you're drafting emails, you can save a quick email ending, as well as your preferred level of formality and a reminder to keep emails to a specific word count, and your drafts will require minimal editing. Copy and paste the key points you would like to convey, press the play button, and send. This only requires less than 90 seconds for most routine e-mails.
For Longer Correspondence
If the email or message is longer, and you want it to have a certain tone, copying and pasting some of your previous successful emails and telling ChatGPT to go with that tone is more effective than describing the tone in the text.
Use Voice Input for Faster Prompting
Why Typing Slows You Down
The writing of a longer, more specific prompt takes longer and frequently produces a shorter, less specific version of the original. Many devices enable the ability to speak into the ChatGPT text box. The natural-sounding way to describe a prompt to a fellow worker will yield more context and improved writing than the shortened version that most people type.
My Honest Take On These Habits
The customized instructions made a difference on their own and were noticeable in just one week. Prior to their implementation, I had to retype the same context at the beginning of nearly each session and was still getting generic outputs that required significant editing. Then, the first answer was typically close enough to use. The prompt library was a more tedious process but also the most time-saving, as the same tasks that I do again and again have already been done and have a very reliable prompt to generate usable output each time that I need it.
Final Thoughts
The divide between users finding ChatGPT useful and those less satisfied is almost entirely due to setup and habit and not the tool itself. Custom instructions, projects, and a small prompt library come with a one-time investment, and they build up over the years. None of them are particularly complex, and between them they move the tool from sometimes useful to a more productive and dependable tool for the majority of the day.
Frequently Asked Questions
Can you use custom instructions in all conversations with ChatGPT?
By default they are applied to all new conversations and can be turned off for a specific session as necessary. Each project has its own individual instructions, which supersede the general custom instructions in that project.
How many projects can be kept up to scratch?
For the majority of people, 3-5 projects is not too many to manage. It is a good idea to start with one for each major area of work.
Can ChatGPT recall conversations from session to session?
Access to conversation history is available in a project. In settings, memory must be enabled, and it holds facts and preferences for conversations, not full transcripts of conversations.
Would it be worth the cost to sign up for a ChatGPT subscription?
Yes, if you are using it for work more than a few times a week. The paid models can process longer documents, multi-step reasoning, and complex tasks much more effectively than the free version; the project feature that makes it easier to do recurring work is only available on paid plans.
